Abstract: The stability against azimuthal Xenon-induced power oscillations is investigated for the e4guilibrium cycle of the 2250 MW(th) core of the HTR-V-project. To this subject three studier are presented . 1. The three-dimensional steady-state core with its neutronic and thermo-hydraulic space functions is very precisely computed using a detailed reactor modele, Resuits are illustrated by means of various Computer plots... 2. The temperature coefficients of the reactivity are determined for the full-load Operation condition ; they resuit to be strongly negative due to the LEU fuel loading . 3. The typical shape and the time-behaviour of Xenon oscillations in the most unstable First azimuthal mode are analyzed with the aid of explicite two-dimensional transient calculations with and withouttemperature feedback. The inherent damping constant of the possible free oscillations is calculated to o.14 h$^{-1}$ and their periodto 35 h.
